Rain began falling mid morning in the greater Nashville area and just after 7 a.m. the sky turned orange then slowly to a shade of green. At one one point it turned yellow.

"We've got some thunderstorms around so it's just some clouds going up to different altitudes reflecting the light around," said Meteorologist Sam Herron with the National Weather Service in Nashville.

"No severe weather is expected and it's not the end of time," he added.

From thoughts of wildfires to Nashville turning into The Upside Down (a Stranger Things 2 reference) dozens of people took to twitter to comment on the strange colors above.

At 7:15, the sky in Nashville was yellow-orange. Like, I thought there were wildfires. @ 7:30, I saw PURPLE lightning 🌩 Goodbye, everyone!
